LAMP-BURNER.

SPECIPICATIQN forming part of Letters Patent No. 358,127, dated February 2 1887- Application filed January 2, 1865. Serial No. 151,7;4. {No model.)

"declare the following to be a full, clear, and exact description of the invention, such as will to pertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My present invention relates to that class of lamp-burners that produce a round blaze by using a flat wick, which, when extended through the wick-tube, meets at the top, forming a continuous circular wick; andmy inven- 53 tion consists in the combination and arrangement of parts, as herein set forth, and pointed out in the claim.

In the drawings forming a part of this specification, Figure l is a longitudinal section through my invention. Figs. 2 and 3 are details of the parts employed for feeding or raising the wick. v

D represents the body or base of my burner,

which is screw-threaded at f for attachment to the lamp-bowl, and is screw-threaded at the 4o tube, 1), which is funnel-shaped.

top, as indicated at a, to which is screwed the tube 25. Said tube surrounds the wick n.

Z is an elbow-shaped tube passing from the top of the burner down and out through the Side of the base D. Said tubeis flaring from the bottom upward, its mouth at being located in the side of the base, through which the air is fed to the center of the flame. Passing through the vertical part of the tube Z is a central Its lower end passes through the horizontal wall of the tube Z, and is anchored to said tube rigidly where it passes through. The upper end of the tubeb supports the disk or spreader O,

5 and said tube is also provided with a venthole, It, forthe admission of air down into the lamp-bowl as the oil is consumed.

Near the top of the base I attach rigidly the common ventilator 1), through which the air "fii sses to the outside of the blazenp-thrtmgh the cone A, which it also supports.

B is the open guard which encircles the lamp-chimney.

These parts are in common use, and need not be particularly described.

I locate the stem 7, which operates the spurwheel, in the month an of the tube Z or airflue. I enlarge the base D at the center, to give sufificient room for the wick a as it folds over the elbow of the tube Z.

It will be observed from the foregoing de scription that the wick n is parted where it passes over the horizontal portion of the tube Z, but is brought together where it enters the tube t. By constructing the central tubes large at the top and smaller at the bottom I am enabled to construct a burner using a wick five inches wide, producing a large clear light, having ample ventilation, that may be readily attached to any ordinary lamp-bowl now in use.

S is a ring having-a serrated outer surface. To this ring I attach the perforated bar 9, its lower end being thrown inward toward the vertical center of the ring S, as shown in Fig. 2, which brings said bar flush with the re-" ceding side of the tube Z, thus throwing the lower end of the bar 9 toward the center of the opening of the lamp-bowl, thus allowing it to pass freely into a lamp-bowl having a small ring or opening for a common burner.

The wick n encircles the ring S, and is held in place by the ring 1%, which surrounds the wick. This ring, however, I do not claim, broadly, the wick n and rings S and B being located between said ring and the tube It, as shown in Fig. 1, and is raised and lowered by the common stem r and spur wheel. Said wheel engages with the series of holes in the bar 9. (See Figs. 1 and 2.) The stem 1' is located in the mouth of the air-flue. The spurwheel passes through the wall of the tube Z, as shown in Fig. 2. I attach to the outer wall of the tube Z the yoke 0, which encircles and supports the bar g. I enlarge the base D of the burner at the center to make sufficient room for the wick in folding over the elbow of the tube Z. The wick is parted where it passes the horizontal portion of the tube Z. Its edges tachcd to tube Z, as specified, and having are joined where they encircle the ring S, the vent-hole 7:, and disk 0, as and for the purmaking a circular wick at the top. poses specified.
